    The effects of the second-layer environments’ cavity number N and the coupling strength κ between two-layer environments on the dynamics of quantum steering have been explored in detail for the weak and strong coupling regimes in this paper based on a quantum system consisting of two qubits, each interacting independently with its own two-layer environments.It has been shown that,with the increase in N and κ, quantum steering presents the oscillation phenomenon, and the survival time and values of which can be improved to some extent.In order to suppress the environmental decoherence, we discuss further the manipulation of quantum weak measurement and measurement reversal on quantum steering.The result shows that quantum steering can be protected effectively by the weak measurement method.
